In 2006, Apple started delivering Macintosh® computers using Intel® processors, and announced that it would transition all of its Macs to Intel processors by the end of 2007. In fact, that transition is already complete. And for Mac users, it means an exceptional level of performance.
The Intel Core 2 Duo processor is a single chip that consists of two processors, and in the new iMac, for example, it delivers up to 50 percent faster performance, executes 64-bit instructions and is available at speeds up to 2.33GHz.
Based on Intel's next-generation Core microarchitecture, the Intel Core 2 Duo offers a second-generation chip born of Intel's new 65-nanometer process. What that process does is enable Intel to create incredibly small transistors — small enough to fit a hundred inside a single human cell. With two powerful processors designed to share resources and circuitry so small, Intel Core 2 Duo not only achieves far higher levels of performance, it achieves it while consuming less power.
Fast system architecture
Adding to the advanced Core 2 Duo processor is an equally advanced system architecture. It includes 4MB of shared L2 cache. That's double the amount previously available. This much bigger L2 cache keeps data instructions close to the two processor cores to increase performance and makes the entire system work more efficiently.
Xserve stands for extra-strength server
 Inside every new Xserve are two 64-bit Dual-Core Intel Xeon processors. Running up to 3GHz, the Xeon processors deliver industry-leading performance in a power-efficient design.
That makes the new Xserve the most powerful Apple server ever — with up to five times the performance of the Xserve G5, according to Apple. Each processor features a 1.33GHz independent frontside bus that maximizes the performance of the system, delivering bandwidth up to 21.3GB/sec.
Four processing cores
Four processing cores deliver an incredible performance boost across the board. And a massive 4MB of shared L2 processor cache per processor — an increase from 512K in the Xserve G5 — increases performance by keeping data and instructions close to the processor core, efficiently sharing cache memory between the two processor cores without duplication of data and reducing system bus contention. Intel's Smart Cache technology allows both cores to share the 4MB of L2 cache; if one core happens to be idle or need less cache resources, the other can fully utilize it.
What's more, since this is the first 64-bit processor based on Intel's next-generation microarchitecture, the 64-bit Dual-Core Intel Xeon processor combines high performance with power efficiency.
In the end, all of this processor technology — and the performance boost it delivers — means if you're a Mac lover, you've got a lot more to love about the Mac.
